Rio Stage 2-6

In level 2-6, you can obtain a 3 star score with either one shot or two. Aim for the edge of the horizontally placed wooden plank that's circled in red. If you can hit the plank without shattering it, it should be pushed into the tower next to it, which will cause a domino effect with the remaining towers. If you're having trouble with this because the first tower breaks on its own, don't fret, a 3 star score is possible with 2 shots. For your second shot, simply aim for the lowest of the horizontally placed wooden planks—the one circled in white. Everything will go down, and the level will be cleared.
